The amp looks good on paper, meets all the criteria I have described. Power supply and transformers specs look good so you should have plenty of reserve power for good bass and dynamics. As I have not listened to any Audio Gd products I cannot make a specific recommendation on this amp as do not know even what the house sound is. The only caveat is that I hope that the top end is not dry as a lot of SS amps tend to be. And the price is too cheap!

post #18 of 34

I was hunting for a vintage SS amp and settled on a Linn Klout but could not find a latest one before it was discontinued. I ended up with another tube amp, a used Copland CTA 504, conservatively rated at 50wpc, for a really good price. This amp is detailed yet very non-fatiguing. My unit has upgrades and some really good tubes. It had 4 EH KT88 reissues. They're alright but the US made GE 6550s are better, deeper, solid bass.
 

BTW, this amp betters my Audio Research D70MkII.

That must sound good. I almost bought a used CTA405. For some reason Canada has always a Copland or two for sale. Reminds me of the uber- expensive Cello by Mark Levinson.

I believe its because there is a dealer in Canada who sells them but not in the US. Mine had the filter caps replaced, some other caps, diodes, and the speaker terminals upgraded with copper from the cheap looking plastic.

 

I met Levinson at his Cello studio in Manhattan way back when, listened to his big demo system. It was impressive.

Have you listened to these on a pure Class A amp that can give it about 6.5wpc and current output of 0.36A?

We had a  headfi meet in Montreal last saturday. One member brought a pair of HE-6 along with the Hifiman EF-6 monster amp and a pair of LCD-3. In the second part of the meet, we have decided to try the HE-6 with my Bryston BHA-1 (pure class A). 

 

What a wonderful synergy! Everybody were really impressed with the sound the combo brought. Extremely high resolution with great punch and tremendous amount of air. I think I even prefer them to the Audeze LCD-3 on my Bryston. But I would like to spend much more time with them to do a real comparaison of the two. The owner of the HE-6 liked the phones much better on my Bryston than on his Hifiman EF-6. He said he finally discovered what these phones are all about. He was about to sell his HE-6 but now, he is considering selling the Hifiman to buy a Bryston or the Mjolnir and keep the HE-6.

 

As power goes, we had to push the Bryston to the maximum on his volume pot on certain songs. But the result was spectacular. I think it's the best experience of headphone listening I had in my existence so far (granted I never listened to Stax).

 

How the Bryston would react with long listening sessions with the HE-6 when push at it's limits? I don't know but the hour or so we use it with the HE-6 gives phenomenal results. And I am not the only one who thought the same. Again, everybody were blown away by the pairing.

I have not specifically listened to a Class A amp that gives out 6.5 watts but having one that puts out 5 watts I think you should be fine with 6.5 watts.

Must be a Canadian thing, EH!

 

I had the same feedback at the Vancouver Head-fi meet. It was a consensus that the HE-6 was the best there at the meet and the best sound ever heard by some from a set of HPs. And this coming from owners of Stax SR-009, Audeze LCD-2's and the Senn HD 800. Quite a statement.

Opinion warning, lawyers need not get excited.

Preproman and I ran the 2.2/6s on the BDA and while it sounded pretty good, the amp was much better suited for the LCD. When you start rocking and reach for the volume knob, the HE will take everything the BDA has and says thank you politely. The sound is superb but the volume is modest. I have not heard the HE sound better than on a good speaker amp with spare power to keep the drivers in check when the program gets complex. Throw a good source in front and with enough power, you won't be able to take the grin off.

I know many think the EF-6 is the perfect amp for the 6s since HiFiMan produced it. I've not heard it but by following the threads for the 6s, the EF-6 will provide adequate power but they do scale better on speaker amps. For their price, you can buy several used speaker amps for a new headphone amp cost.

Tomorrow, Preproman and I will get an opportunity to visit an A/V dealer to try the 6s on some higher end amps to see how they scale with higher performance than we currently have.

IMO

The BHA-1 may be a pure Class A amp, but it just does not have the juice to make the HE-6 sing.  We had the volume knob all the way to the max and the HE-6 said "Give Me More" Just like on my B22.  Happy Camper is right.  The HE-6 scales wonderfully with more current / power what ever you want to call it - these "CANS" need a speaker amp to reach its' full potential.

I agree. The 3.8W that BHA-1 puts out @ 50 just won't do  justice to the HE-6.  If you think it sounded good with the BHA-1, imagine what it will sound like if you have a decent pure class A amp that puts out more like 6 Watts+@50. Sublime!

This is exactly what I'm shooting for.

According to Stuart Taylor, Chief-engineer at Bryston, the BHA-1 can output a maximum of 20 volts by channel. That will translate in 8 watts if my current calculator is exact. They are some wrong specs on the data sheet of the BHA-1 Mr. Taylor told me in an email communication a couple months ago. Like power output. I don't have any tools to confirm his sayings.

 

That being said, it's absolutely true that even at full output of the BHA-1, the HE-6 wants more juice. Despite that, the result was spectacular. But I am sure a more powerful amp (or a speaker amp in that matter) would increase the HE-6 already spectacular performance.

Time to call Chris Russell. I wonder if he would remember me. I was the only one of three friends that did not buy a Bryston on a visit to their factory when they were just starting out in late70s/early 80s.

 

Yeah, I looked at their specs and it says

 

  • Rated at 500 milliwatts per channel into 32 Ohms

 

  • Maximum 6 Watts per channel into 32 Ohms (at 1% THD)

 

So 8 watts would be more like 10%+ distortion-tho this is purely speculative on my part based on the above. Also because of the chassis size I doubt it can output even 6 watts@50 Ohms of pure class A  at sustained levels without burning itself to death. That's like 120w of heat dissipation and no heat sinks!

 

I wonder if the speaker amps sound better on the HE-6, because their distortion figures are comparably much lower at similar power levels.

I believe this has something to do with no sound that I can detect if the material is clean. Dead quiet. But the dynamics and blossoming of the soundstage has to do with the power supply and the output design/components. I'd be curious to see what the current draw is on the drivers at moderate listening levels. Read note 2 http://www.audioholics.com/education/amplifier-technology/10-things-about-audio-amplifiers

On a side note, the first cable that came with my 6s is almost completely green now. I have a new cable I store in a zip-lock baggie with a nitrogen purge. I'm interested in hearing any suggestions on how to possibly seal the ends to prevent oxidation. It will be some time before I hard wire them with a cable upgrade. I have other dragons to slay.
